' 1 Application fi'lc d Marten 17,

- .-This invention relates to improvements in fit'orpedo'es and more particularly to the depth regulating mechanism.

' the horizontal rudder. It is also customary to provide means temperatures in for regulating the ,depth.

'Owmg, however, to the exceedingly high pedo which causes more or less expansion and contractionpf the various parts,"the

depth regulating mechanism is not always uniform throi'ighout' the. entire run and it is, therefore, oneof the objects of the present invention to provide a more reliable and efiicient mechanism for maintaining uniform depth. j

A further object is to provide a simple and practical mechanism which will be water-cooled thereby avoiding someof the above objections.

A further object is to provide an improved setting mechanism for the depth-gear whereby the same may be easilyand quickly operated.

A further object is -to provide a mechanism of the above character which may be installed in torpedoes now in use Without material alteration of the mechanisms or parts now contained therein.

, Other ob 'ects will be in part obviousand in part hereinafter pointed out in connection with the accompanying sheets of drawings forming a part of the present disclosure and in which drawings corresponding parts are denoted by similar reference characters.

In these drawings, Figure 1 is a diagrammatic view of the after-body of atorpedo showing the relative location of the depth control mechanism and the setting mechanism therefor.

Figure 2 is a partial sectional plan view of the depth control mechanism,

Figure 3 is a sectional view taken substantially along the line 3/3, Figure 2.

Figure 4 is a sectional view taken substantially at right angles to Figure 3, certain parts being omitted for the sake of clear ness.

The shaft 12 1S provided with a worm 27' coactin'g wlth a pinion .28 which constitutes a -"dial or indicating mechanism visible through an opening 30. This pinion 28 is moved proportionally to the setting mechanism 6. diaphragm plate. 21 is attached a shaft 31 which connects through a hell crank lever 32 connected with the steering engine to a pull rod 33 extending aft in the torpedo forconf trolling the horizontal rudder.

The air chamber 24 is adapted to be fastened to the present gyro base and a diaphragm plate 21 acts against the leverage 31, 32 and 33 as above described. The tension of the spring 18 is varied by turning the adjusting screw through the gears indicate the setting of the spring and check up the regular setting dial on thetop of the torpedo as indicated at 6. t
